Introduction

The River Red Gum (Eucalyptus camaldulensis) is a tree of the genus Eucalyptus, and is found across most of Australia especially beside inland water courses. It usually grows to 20 metres, sometimes up to 45 metres tall; its bark streaked and mottled with red, grey and white. The tree produces welcome shade in the extreme temperatures of central Australia, and plays an important role in stabilising river banks, holding the soil and alleviating flooding. The "snags" formed when River Red Gums fall into rivers such as the Murray are extremely important sites for the functioning of river ecosystems, and incredibly important habitat and breeding sites for native fish like Murray Cod. Unfortunately most snags have been removed from these rivers. Species About 700; see the List of Eucalyptus species Wikispecies has information related to: Eucalyptus Eucalyptus is a diverse genus of trees (rarely shrubs), the members of which dominate the tree flora of Australia. ... In Australia, the trees, branches and other pieces of naturally occurring wood found in a sunken form in rivers and streams are called snags. ... Trinomial name Maccullochella peelii peelii (Mitchell, 1838) The Murray Cod (Maccullochella peelii peelii) is the largest freshwater fish in Australia. ...


River Red Gums only germinate when land is flooded. As a result, its numbers are declining due to increased water management. The largest remaining stand of River Red Gum is in the Barmah state forest in the north of Victoria. Red gum is an excellent firewood and a very striking timber. The Barmah forest is carefully managed to produce both fine timber and firewood.


Red gum is so named for its brilliant red wood, which can range from a light pink through to almost black, depending on the age and weathering. It is somewhat brittle and often has a wiggly grain making hand working difficult. It is quite hard and can take a fine polish and carves well. It is a popular timber for wood turners, particularly if the timber has been used for structural work, or fence posts first.


The wood can be used for charcoal production, what is successfully applied in Brazil iron, steel, and seamless steel tubes companies.


River Reds have a more sinister name, "Widow Maker", as they are notorious for dropping large (often half the diameter of the trunk) boughs without warning. This may be a means of saving water (though some people believe otherwise).


The Greenough([1]) form has a strange growth habit, turning 90 degrees from vertical just above the ground.


It is regarded as one of the most widely planted eucalypts in the world (ca 5,000 km² planted) (NAS, 1980a). Plantations occur in Argentina, Arizona, Brazil, California, Egypt, Kenya, Morocco, Nigeria, Pakistan, Senegal, Sierra Leone, Spain, Sri Lanka, Sudan, Tanzania, Upper Volta, Uruguay, and Zimbabwe.


Formation of the Barmah Red Gum Forests

The formation of the famous Barmah Red Gum Forests is due to a relatively recent geological event in the Murray-Darling Basin involving the Cadell fault. Semi-arid grazing country near Burra Creek, South Australia The Murray-Darling Basin drains one-seventh of Australia and is by far the most significant agricultural area on that continent. ...


About 25,000 years BP, displacement occurred along the Cadell fault, raising the eastern edge of the fault (which runs north-south) 8-12 metres above the floodplain. This created a complex series of events. A section of the original Murray River channel immediately behind the fault was abandoned, and exists today as an empty channel known as Green Gully. The Goulburn River was dammed by the southern end of the fault to create a natural lake. The Murray River flowed to the north around the Cadell Fault, creating the channel of the Edwards River which exists today and through which much of the Murray River's waters still flow. Then the natural dam on the Goulburn River failed, the lake drained, and the Murray River avulsed to the south and started to flow through the smaller Goulburn River channel, creating "The Barmah Choke" and "The Narrows" (where the river channel is unusually narrow), before entering into the proper Murray River channel again. The Murray River, or River Murray, is Australias second-longest river in its own right (the longest being its tributary the Darling). ... Goulburn River is either: Goulburn River, New South Wales, Australia Goulburn River, Victoria, Australia This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... Edwards River may refer to: The Edwards River in New Zealand The Edwards River in Illinois in the United States This is a disambiguation page: a list of articles associated with the same title. ...


The primary result of the Cadell Fault however is that the west-flowing water of the Murray River strikes the north-south running fault and diverts both north and south around the fault in the two main channels (Edwards and ancestral Goulburn) as well as a fan of small streams, and regularly floods a large amount of low-lying country in the area. These conditions are perfect for River Red Gums, which rapidly formed forests in the area. Thus the displacement of the Cadell Fault 25,000 BP lead directly to the formation of the famous Barmah River Red Gum Forests.


Cultivation

E. camaldulensis readily germinates from both fresh seed and seed stored in cool dry conditions. It quickly toughens up and can withstand drought even whilst in forestry tubes. It makes an excellent bonsai and will readily regrow both from the base and from epicormic buds. i enjoy male penis

Eucalyptus camaldulensis (3638 words)
Stands of river red gum are intimately associated with the surface-flooding regime of the watercourses and related ground water flow.
The river red gum and sedge-rush community occurred in riparian habitats where current was slow and the bank was gently sloping and not subject to strong wave action.
Regeneration of river red gum was recorded at several channel edge localities, especially where the channel bank was not far elevated from the anabranch creek level (O'Malley and Sheldon, 1990).
